JPMorgan Chase has reported financial results for the first quarter 2012. Highlights include:

Net income was $1.2 billion, a decrease of $351 million, or 23%, compared with the prior year. The decrease reflected a higher provision for credit losses, driven by a lower reduction in the allowance for loan losses compared with the prior year.

Card Services net revenue as a percentage of average loans was 12.22%, compared with 12.18% in the prior year and 12.26% in the prior quarter.

Credit Card sales volume (excluding commercial cards) was $86.9 billion, up 12% compared with the prior year and down 7% compared with the prior quarter; excluding the impact of the Kohl’s portfolio sale, sales volume was up 15% compared with the prior year.
